Believers are “the temple of the living God,” in which he dwells and walks, 2 Cor. vi. 16. Every one of them is a little sanctuary and temple to his Majesty, “sanctify the Lord of hosts in your hearts.” Though he be “the high and lofty One that inhabits eternity,” yet he is pleased to come down to this poor cottage of a creature’s heart, and dwell in it. Is not this as great a humbling and condescending for the Father to come down off his throne of glory, to the poor base footstool of the creature’s soul, as for the Son to come down in the state of a servant, and become in the form of sinful flesh? But then he is a temple and sanctuary to them. “And he shall be for a sanctuary,” (Isa. viii. 14.) a place of refuge, a secret hiding place. Now, as every one is a little separated retired temple, so they all conjoined make up one temple, one visible body, in which he dwells. Therefore Peter calls them “living stones built up a spiritual house” to God, 1 Pet. ii. 5. All these little temples make up one house and temple fitly joined together, in which God shows manifest signs of his presence and working. Unto this the apostle in this place alludes. The communion and union of Christians with God is of such a nature, that all the relations and points of conjunction in the creatures are taken to resemble it and hold it out to us. We are citizens, saith he, and domestics, household-men, and so dwell in his house, and then we are this house besides. Now ye know there are two principal things in a house—the foundation and the cornerstone, the one supports the building the other unites it and holds it together. These two parts of this spiritual building are here pointed at. The foundation of every particular stone, and of the whole building, is the doctrine of the prophets and apostles, as holding out Jesus Christ to souls, “the rock on which our house shall be builded,” not the apostles or prophets, far less pastors and teachers since,—for they are but at best, “workers together with God, and employed in the building of the house,” nor yet their doctrine, but as it holds out that “sure foundation” that God has laid in Zion, (Isa. xxviii. 16.) which is Jesus Christ for “other foundation can no man lay.” And then, “the corner stone” is that same Jesus Christ, who reaches from the bottom even to the top of the building, and immediately touches every stone, and both quickens it in itself, and unites them together.
